Astigmatism

Astigmatism is a common eye condition that occurs due to an irregular curvature of the cornea or lens, leading to a distorted image on the retina. In simple terms, when the shape of the eye prevents the light from focusing on a single point, the person experiences blurriness or distortion in both distant and close-up vision. The severity of astigmatism varies, and it may occur alone or alongside other refractive errors like myopia or hyperopia. It cannot be prevented but can be easily diagnosed through a comprehensive eye exam and corrected with eyeglasses, contact lenses or refractive surgery. Astigmatism can cause eye strain, headaches, squinting, and difficulty seeing at night or while driving. It can affect people of any age and may be hereditary. Fortunately, it does not lead to blindness and can be well managed with proper eye care. In conclusion, astigmatism can be a significant hindrance to an individual’s quality of life, but it is easily treatable with modern ophthalmic science.
